is it running out_of_the_box as stated in the doc ?

I installet it as stated in the doc , but when upon index view display I get :
Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id
Extracted source (around line #2):
1:

2: <%= hidden_field_tag(:wf_id, wf_filter.id) %>
3: <%= hidden_field_tag(:wf_type, wf_filter.class.name) %>
4: <%= hidden_field_tag(:wf_dirty, "false") %>
5: <%= hidden_field_tag(:wf_submitted, "false") %>

trace beginning giving :
